For spotted lanternfly concerns, applying on lawn edges, tree bases, and around susceptible plants can help reduce adult and nymph activity when used as part of an integrated pest management approach.
Bonide Systemic Houseplant Insect Control

Bonide Systemic Houseplant Insect Control uses a granular, root-absorbed formulation to protect containerized plants indoors and outdoors. The systemic action moves through the plant and provides protection for up to eight weeks against a variety of insects such as mealybugs, aphids, and scale.

It is suitable for use on vegetables, ornamentals, shrubs, and fruit trees, including applications on edible crops up to the day of harvest. The product is best for soft-bodied insects and is often used to address lanternfly nymphs and aphids on a variety of plant types, particularly in garden beds and around landscape plants.
Bonide Insecticidal Soap

Bonide Insecticidal Soap offers a multi-purpose, outdoor residential solution for organic gardening. With direct-contact and ingestion modes, it targets a broad range of pests including aphids, mites, caterpillars, and scale. While not specific to lanternflies, it can be part of an integrated approach to managing soft-bodied pests on vegetables, ornamentals, and fruiting plants, reducing lanternfly feeding pressure on susceptible hosts.
